I think a good work-around and improvement would be to change the randomization function to favor certain URLs: - earlier == higher probability - visible == higher probability - clickable == higher probability But, keep it random and allow even late/invisible/unclickable to be queried so we can't be completely fooled by some HTML trick. > Perhaps we'll need a rule to look for "too many URIs" in a message. <G> DOMAIN_RATIO. :-) -- Daniel Quinlan ApacheCon! 13-17 November (3 SpamAssassin http://www.pathname.com/~quinlan/ http://www.apachecon.com/ sessions & more)
